Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If microscopic imaging and machine learning are used for authentication, then authentication accuracy is improved, but device complexity and cost increase
Solution Approach 1:
The patent uses smartphone camera images as copies of the product specifications instead of requiring microscopic imaging equipment. The machine learning model processes these standard camera images to achieve authentication, replacing complex specialized equipment with ubiquitous smartphone technology.
Solution Approach 2:
The invention replaces expensive specialized imaging equipment with inexpensive smartphone cameras that consumers already possess. This cost-effective approach eliminates the need for high-cost microscopic imaging devices while maintaining authentication capability.
2Measurement precision
If multiple images from different aspects are captured for authentication, then authentication accuracy is improved, but ease of operation deteriorates
Solution Approach 1:
The patent merges multiple authentication requirements into a single image capture operation. Instead of requiring consumers to capture multiple images from different aspects, the system processes a single smartphone image to determine authenticity, significantly reducing user effort while maintaining accuracy.
3Measurement precision
If microscopic feature analysis is used for authentication, then authentication accuracy is improved, but processing speed deteriorates
Solution Approach 1:
The patent uses standard smartphone camera images instead of microscopic imaging data. This approach processes images at a much faster rate since they don't require the time-consuming capture and processing of microscopic features, while still achieving accurate authentication through machine learning.
4Ease of manufacture
If camera bias is introduced in training data, then model training is simplified, but measurement precision deteriorates
Solution Approach 1:
The patent applies local quality transformations (cropping, rotating, adjusting brightness and contrast) to training images to enhance features without introducing camera bias. This allows the model to learn authentic local characteristics of product specifications while maintaining training simplicity and achieving high predictive accuracy.
